GONDENSATION RECEIVER AND PUMP.

Specification of Letters Patent.

Application filed January 8, 1921. Serial No. 435,883.

objcctof my invention is to produce an ex ceedingly simple and absolutely automatic structure which'will receive and handle water at a higher temperature than ordinary pumps, and deliver it to the boiler or wherever desired regardless of pressure- My invention is intended to produce a fuel savingapparatus which will eliminate piston and centrifugal pumps, pump governors, etc, in many installations, and which is useful as aste'am: trap or condenser to receive the return steam and water of condensation in buildings and automatically deliver 1t to the boiler; My invention can also be used as a jet condenser, and to transport Oil or other liquid by using compressed an? from one point to another. It' can also be used for receiving and dehvering sewage up to the main sewer in buildings where the lower floors are below the main sewer line. In carrying out my invention, I employ a pair of tanks which alternately receive and discharge water of condensation, or other liquid, and which tilt automatically as they are filled and discharged, and automatically cut oil the pressure fluid whether it be air, steam, or the like. The invention will'be better understood from the description which follows.

Reference is to be had to the 21(!( 301I1Pa11f{ ing drawings. forming a part of tlus specification, in which similar reference characters indicate corresponding parts in all the views; 7 v

Figure 1 is a side elevation. of the apparatus embodying my invention.

Figure. 2, is a plan view thereof.

Figure 3 is a detail view partly in sectionof one of the tanks: and some of its connections.

Figure at is a. broken vertical sectional view showing the port connections at the foot off one of the tanks.

Figure 5 is a detail of oneof the valve arrangements for'cutting oil the pressure fluid from the tanks alternately,

F'gure 6 is a modification of the struc ture shown in Figure 5, and

Figure 7 is a detail of the air relief valve. The apparatus can be mounted in anv suitable frame, and I have shown it provided with a base 10' having a central framework 11' and an arched frame work 12, serving to support and guide the tanks and the operating connections. I employ apair of tanks 13 and 14 which are exactly similar and which have similar connections, so that the description ofthe connections of one applies equally to the other. Each tank has a relatively large pipe 15 opening from the bottom and vertically arranged, which is provided with mta ke and (lllSCllftlge ports 16 and 1'7, adapted to register with the in-v let and discharge ports 18 and 19 in the pipe 20, which is vertically arranged on the base 10, and these pipes 20 serve in a manner as dash-pots as well as valve casings. It will be seen that when the tank is in its raised position, the port 16' will registcr'with the port 18,-so that the inflow can pass to the raised tank, but the port 17 will be above the port 19, and the latter will be closed by the apron 21. A similar apron 22 balances the pipe 15 and slides inthe pipeQO. 7 It will be seen, therefore, that the port- 18 is opened only when its tank is receiving the inflow of water,-. opened only when the tank is depressed and the liquid is being ejected.

These pipes 20 connect by a circulation pipe 23 having a valveQAlby which the rapidity of the circulation can be regulated, and thus byproviding the resistance when the tank drops, a dash-pot effect is :had withoutinterfering with the operation of the structure. The tanks are pivotally connect ed on opposite sides to links 25 whiclnarc pivoted to walking beams 26, these being pivoted in the supports 11 so that the tanks will rise and fall alternately. They can be.

guided in any suitable way. The pipe 15 serves in a measure as aguide, and they can be :turther guided. 'byrods- 28 attached to the tops of. the tanks and ,extendin through the upper part of the arche frame 12. c

To prevent the tanks from tipping too soon they are temporarily locked with one tank in its. lower position by the following means.

Each tank has near the bottom. abail 29 which extends downward between spring latches 30 adapted to snap over the bail,

and the port 19 will be and these pass through a keeper 31 supported by an arm 32 or equivalent support, and the tension of the latches can he regulated by the screws 33. Thus they can bev adjusted so that when the full tank is down as shown at the left inFigure 1, the latches will engage the bail 29, but as the tank it becomes empty and the tank 13 full; the weight of the latter will cause it to drop, thus raising the tank 14 and releasing it from the latches 30. i

The pressure fluid is admitted to the tanks from apipe 3iwhich can connect with the boiler pressure or with asource of compressed air or other pressure fluid. This pipe connects with a cross pipe 35 which in turn connects with the vertical valve casings 36 in each of which is a piston 37 adapted to close the end of the pipe 35. The pistons 37 connect on the underside by means of rods 38 with links 39 which are pivoted to one ofthe walking beams 26. Thus when the tanks are in the position shownin Figure 1, it will be seen that the valve casing 36 connecting with the tank 14 will be open to admit pressure fluid to said tank and facilitate the discharge of material therefrom, whilethe pressure fluid will be shutoff from the tank 13, and as the positions of the tanks change, the valves will also change, obviously. One valve cas ing 36- connects. by the pipe 40 with, the

a tank 13, and the other by a pipe 40 with the tank 14. In detail the pipes 40 and 40* connect with pipes 41, and these with vertical pipes 42 having a sliding connection with the pipes 43 on the tanks 13 and 14. Each pipe 41 is prolonged and connected with a valve casing 44 in which is a piston ,valve 44, the piston rod 46 of which pivotally connects with a lever 47 which is pivoted at one end to the tank by means of links 49, and at the other end is pivoted toa support or bracket 48 on the frame 12.. Thus when the tank is being filled, the valve 44 will be open to permit the escape of air, but when the tank is full, it will be closed so that pressure fluid may properly work on the contents of the tank. As an additional safeguard to insure the cutting of of pressure fluid, instead of having the construction shown in- Figure 5 for cutting ed the pressure fluid, the modification shown in Figure 6 can be In this case the pipe 34 connects by-a branch pipe 50 with opposite ends-of a horizontally arranged cylinder 51 in which slides a piston 42 adapted to alternately open and close the pipes 40 and 40, and the piston rod 53 connects by a link 54 with a bell'cra'nk 55 which is pivoted as shown at 56, and can be suitably connected with one of the tanks or arms 39 to operate the valve. As an additional safeguard to make sure that the steam is shut ofi when a tank is empty, each tank is provided with a float 57 connected to a rod 58 which is secured to a shaft 59 extending from a suitable stufiingbox in the shell of the tank, and. theishaft is provided with a crank (50 havinga loose connection with a 'rod 61 suitably mountech'and this pivotally connects by means of a link 62 and arm 63 with a valve 64, This loose connection in the present instance comprises a sliding connection 60 between the crank 60 and the rod 61, said sliding connection being in the form of a ring which rcciprocates between the collars 60 and 60 which are spaced apart and fixed to the rod, As the crank (50 swings up or down, the member 60 will slide correspondingly, having a lost motion between the collars 60 and 60, and the rod 61 swinging on its pivot permits this action. When the ring 60 strikes either collar, it moves the rod 61 down or up as the casemay be, and so actuates the valve 64.

From the foregoing description it will be seen that 'I have provided a simple and positive structure which works automatically, and can be easily applied. to any of the purposes stated. 7 When a tank is full it drops as shown at the left hand in Figure 1, and the empty tank rises, and by the mechanism described pressure fluid is admitted to the full tank soas to force the liquid therefrom,fwhile the pressure fluid is automatically cut off .from the empty tank. The waterwill then flow into the empty tank, the air meanwhilepassing out through the reliefwalve 44, and when the second tank full, it drops and the action described, is repeated. Thus it will be seen that when the apparatus is installed and started, work as long as are supplied.
